MANUFACTURING METHOD OF CATALYST INK, MANUFACTURING METHOD OF FUEL CELL, AND FUEL CELL

摘要

A catalyst ink for improving the performance of catalyst electrodes in a fuel cell is produced by the following procedure. A catalyst dispersion is prepared by dispersing catalyst-supported particles as conductive particles with a catalyst supported thereon in a solvent. A gel material having viscoelasticity is prepared by mixing an ionomer with a volatile solvent. A catalyst ink having a desired viscosity is produced by stirring and mixing the catalyst dispersion with the gel material.

1. A manufacturing method of a catalyst ink used for formation of a catalyst electrode, the manufacturing method comprising steps of:
(a) dispersing catalyst-supported particles as conductive particles with a catalyst supported thereon in a solvent to prepare a catalyst dispersion; (b) mixing an ionomer with a volatile solvent to prepare a gel material; and (c) stirring and mixing the catalyst dispersion with the gel material to produce a catalyst ink.
